Introduction

About this Manual

This manual provides information on the Extron DA AV EQ series of audio/video distribution amplifiers and discusses how to install and operate them.

The terms “DA,” “amplifier,” and “distribution amplifier” are used interchangeably to refer to any of the models in the

DA AV EQ series.

About the DA AV EQ Series

The Extron DA AV EQ Series products are high-performance composite video or S-video distribution amplifiers with audio. Models with audio only and video only are also available. The DA AV EQ series amplifiers feature long cable drive capability and individual gain and equalization adjustments (for every two outputs) to optimize the picture for displays that are located at significantly different distances from the DA.

Models

The DA AV EQ Series consists of the following 10 models:

DA 6V EQ — One input, six outputs, composite video with equalization and gain controls

DA 6AV EQ — One input, six outputs, audio, and composite video with equalization and gain controls

DA 6AV RCA EQ — One input, six outputs, audio on RCA connectors, and composite video with equalization and gain controls

DA 6SV EQ — One input; six outputs; S-video with luma (Y) equalization control, and luma and chroma gain controls

DA 6SVA EQ — One input; six outputs; audio; and S-video with luma (Y) equalization control, and luma and chroma gain controls

DA 6SVA RCA EQ — One input; six outputs; audio on RCA connectors; and S-video with luma (Y) equalization control, and luma and chroma gain controls

DA 6A — One input, six outputs, audio only

DA 3AV RCA — One input, three outputs, audio on RCA connectors, and composite video

DA 12V/6V Dual EQ — Dual composite video DA that can function as either a 1-input, 12-output DA with one active loop-through, or two 1-input, 6-output DAs in one enclosure (no loop-through); equalization and gain controls

DA 8V/4V Dual EQ — Dual composite video DA that can function as either a 1-input, 8-output DA with one active loop-through or two 1-input, 4-output DAs in one enclosure (no loop-through); equalization and gain controls

Features

Equalization and gain control — Independent gain and equalization control for each two outputs provides more flexibility and more accurate cable compensation to drive different lengths of cables from different outputs. (S-video models have Y-only equalization, and Y and C gain controls.)

Outputs with similar lengths of cables should be paired in the same output group so that they can share the same gain and EQ setup.

Passive video loop-through — All models except DA 6A, DA 12V/6V Dual EQ, and DA 8V/4V Dual EQ feature a passive video loop-through channel with a 75 ohm impedance toggle switch, which provides for local monitoring and cascading to another distribution amplifier.

Power supply — An internal 100 VAC to 240 VAC, 50/60 Hz, autoswitchable power supply is provided on all models.

Enclosure — All models have a compact 1U, half rack enclosure, six inches in depth.

High bandwidth — Bandwidth of 150 MHz @ -3 dB for composite video and S-video maintains signal quality without picking up noise.

Rack and furniture mountability — All models can be mounted on a rack shelf, under a desk or podium, or through a desk or table top.

Rack mounting

UL rack mounting requirements

The following Underwriters Laboratories (UL) requirements pertain to the safe installation of the equipment in a rack.

1. Elevated operating ambient temperature — If the equipment is installed in a closed or multi-unit rack assembly, the operating ambient temperature of the rack environment may be greater than room ambient temperature. Therefore, install the equipment in an environment compatible with the maximum ambient temperature (Tma = +113 °F, +45 °C) specified by Extron.

2. Reduced air flow — Install the equipment in a rack so that the amount of air flow required for safe operation of the equipment is not compromised.

2-2 DA AV EQ Series • Installation and Rear Panel

3. Mechanical loading — Mount the equipment in the rack so that a hazardous condition is not achieved due to uneven mechanical loading.

4. Circuit overloading — Connect the equipment to the supply circuit and consider the effect that circuit overloading might have on overcurrent protection and supply wiring. Appropriate consideration of equipment nameplate ratings should be used when addressing this concern.

5. Reliable earthing (grounding) — Maintain reliable grounding of rack-mounted equipment. Pay particular attention to supply connections other than direct connections to the branch circuit (e.g., use of power strips).

Rack mounting procedure

Mount the DA AV EQ through a desk or table, using the optional through-desk mounting kit (part #70-077-02).

Through-desk mounting the DA AV EQ

1.

Mark the opening through which the unit will be

 

mounted — approximately 1.8" by 8.9" (4.6 cm by 22.6 cm).

2.

Cut out the material from the installation area with a

 

jigsaw.

3.

Drill pilot holes 1/4" (6.4 mm) deep and 3/32" (2 mm) in

 

diameter in the desk or table at the locations of the

 

mounting bracket screws. The holes should be drilled

 

from the underside or inside (concealed side) of the

 

furniture where the amplifier will be located.

4.

Using the four provided wood screws, attach the brackets

 

to the mounting surface.

5.

Slide the unit up and down or back and forth in the

 

mounting brackets until the face of the DA is at the desired

 

height. Tighten the screws that secure the bracket in place.

 

If the screws are inaccessible to a screwdriver,

 

a.

Mark the location of the brackets relative to the

 

 

screws.

 

b.

Remove the DA from inside the furniture.

c. Tighten the screws.

d.

Replace the DA inside the surface (repeat step 4).

Setting the Audio Output Gain

On the DA 6SVA EQ, DA 6AV EQ, and DA 6A audio models, you can set the gain for the left and right channels independently.

This applies only to models with captive screw audio connectors.

On the internal board, each audio output has a set of jumpers (one left and one right). By placing these jumpers on the appropriate pins on the board, you can set the gain for each channel to -6 dB, 0 dB, +6 dB, or unity, depending on whether the output is wired for balanced or unbalanced audio.

To set the gain for an output channel using the internal jumpers,

1.

Using an Extron Tweeker or other small Phillips

 

screwdriver, remove the six screws from the sides and top

 

of the unit, and carefully lift off the top cover.

2. By default, all jumpers are on the middle and right pins for each output’s right and left channel — the configuration for balanced audio. (See the photograph on the next page.)

Jumpers on the internal board in their default (balanced) position

To change any output channel to unbalanced audio, lift the jumper off the middle and right pins, and place it on the left and middle pins, as shown in the following illustration.

Gain and Equalization Controls

To set up your DA AV EQ, you may need to adjust the gain and equalization (EQ) for the output cable lengths. Gain and EQ are adjusted from the front panel of all DA AV EQ series products except the DA 6A and DA 3AV RCA. On S-video models, you can adjust luma (Y) gain and equalization, and chroma (C) gain. On composite video models, you can adjust Gain and EQ. Adjustments are made for each pair of outputs.

Gain and EQ potentiometers (pots) on the front panels enable you to make gain and equalization adjustments. Each pot has a white dot either above it (composite and Y gain) or to the lower left of it (EQ and C gain). These dots indicate 0 dB unity.

Use an Extron Tweeker or a small Phillips screwdriver to rotate these pots clockwise to increase gain or equalization, or counterclockwise to decrease.

The DA AV EQ products have one EQ pot and one or two Gain pots for each pair of outputs. Therefore, gain and equalization can be adjusted only for a pair of outputs at a time. For example, if you adjust the equalization pot for output 1, output 2 is automatically adjusted at the same time and by the same amount, .

This means that you should have cables of the same length for both outputs of a pair.

DA 6V EQ, DA 6AV EQ, DA 6AV EQ RCA,

DA 8V/4V Dual EQ, and DA 12V/6V Dual EQ — The front panels of these models feature one Gain and one EQ pot for each pair of outputs. The illustration below shows the Gain and EQ pots for outputs 1 and 2.

Settings for short cables

At the factory, the DA AV EQ pots are set precisely to the unity gain position (with the arrow on the pot pointing to the dot beside or above it). If you are using very short output cables, do not turn these pots; leave them at the factory default setting. If the pots have already been turned, reset them to the default position.

Adjusting for long cables

If you are using long cables, you need to adjust the Gain and EQ potentiometers (pots) until you have the best picture quality. Using an oscilloscope is recommended; however, you can make these adjustments without one. Both methods are described below.

Adjusting with an oscilloscope

1.Feed a grayscale signal from an Extron VTG 300/400 or other A/V test generator to the input of the DA AV EQ.

2.Remove the far end of the output cable from the display, and connect it to the oscilloscope with 75 ohm termination.

3.Adjust the composite video or Y Gain pot to achieve 0.7 Vp-p for the white bar of the test pattern. For the

S-video models, adjust the C gain pot to achieve 0.3 Vp-p of color burst level.

4.Adjust the EQ pot until no overshooting or round corners appear on the test pattern.

5.Repeat steps 1 through 4 for all other output pairs.

6.

Plug the far end of the cable back into the display device.

Adjusting without an oscilloscope

1.Feed a grayscale signal from an Extron VTG 300/400 or other A/V test generator to the input of the DA AV EQ.

2.Adjust the composite video or Y Gain pot until the picture from the display device appears to have the correct brightness and contrast.

3.Adjust the EQ pot until the picture appears sharp and without visible smearing.

4.

Repeat steps 1 through 3 for all other output pairs.
